The Charleston Bump rises up from a deep plateau, over 2,000 ft deep, to a depth of about 1,200 ft. Because of its vertical profile, it acts like a very deep reef and attracts many species of marine organisms. In U.S. waters, the large, grouper-like wreckfish (above) is abundant only on the Charleston Bump, which is also the only known wreckfish spawning ground in the western North Atlantic.
